It seems like the intention is to re-start the rectangle on mouse-1?  I
don't use the mode either, but that does seem to make sense to me.

(defun cua-mouse-set-rectangle-mark (event)
  "Start rectangle at mouse click position."
  (interactive "e")
  (when cua--rectangle
    (cua--deactivate-rectangle)
    (cua--deactivate t))
  (setq cua--last-rectangle nil)
  (mouse-set-point event)
  ;; FIX ME -- need to calculate virtual column.
  (cua-set-rectangle-mark)
  (setq cua--buffer-and-point-before-command nil)
  (setq cua--mouse-last-pos nil))

And I guess the "FIX ME" is part of the problem here.  Anybody else got
any insights here?
